Description

Technical Field

[0001] The invention relates to a control method for an air conditioner. Background Art

[0002] In the existing control method of the air conditioner, the controller temperature and the indoor unit temperature are obtained by temperature sensors set in the controller and the indoor unit of the air conditioner, and the indoor ambient temperature is compensated according to the difference between the controller temperature and the indoor unit temperature and the power-on time of the controller to calculate the indoor ambient temperature, thereby controlling the operation of the air conditioner according to the indoor ambient temperature.

[0003] However, since the controller of the air conditioner has the problem of self-heating, and there are many factors affecting the temperature of the indoor unit (installation location of the indoor unit, model, location of the air outlet and air inlet, operation mode, etc.), in addition, the temperature compensation method in the prior art only considers the power-on time of the controller and the difference between the controller temperature and the indoor unit temperature. Therefore, there may be a large error between the calculated indoor ambient temperature and the actual indoor ambient temperature, thereby affecting the use effect of the air conditioner and the user experience. Therefore, the problem that follows is how to make the calculated indoor ambient temperature closer to the actual indoor ambient temperature with a relatively simple hardware structure and improve the accuracy of the calculated indoor ambient temperature. Summary of the invention

[0004] The present invention is completed based on the above-mentioned problems, and its purpose is to provide a control method for an air conditioner, which can make the calculated indoor ambient temperature closer to the actual indoor ambient temperature with a relatively simple hardware structure, thereby improving the accuracy of the calculated indoor ambient temperature.

[0005] In the control method of the air conditioner of the present invention, the air conditioner includes: a controller; and a temperature sensor, which is arranged in the controller, and the control method includes: a collection step, in which the current temperature of the controller is obtained through the temperature sensor when the controller is powered on; a judgment step, based on the power-on time of the controller and the operation mode of the air conditioner, the current state of the air conditioner is determined; and a calculation step, according to the current state, and at least any one of the power-on time of the controller and the duration of the operation mode, the compensation temperature is determined, and the difference between the current temperature and the compensation temperature is calculated as the indoor environment temperature.

[0006] Thus, the control method of the present invention obtains the current temperature of the controller and calculates the compensation temperature based on the power-on time of the controller, the operation mode of the air conditioner, and the duration of the operation mode, thereby calculating the indoor ambient temperature. Therefore, under the premise of ensuring that the hardware structure is relatively simple, the calculated indoor ambient temperature is closer to the actual indoor ambient temperature, thereby improving the accuracy of the calculated indoor ambient temperature.

[0007] In addition, in the control method of the air conditioner of the present invention, when the power-on time of the controller is less than the set time threshold, or when the power-on time of the controller is not less than the set time threshold, and the operation mode of the air conditioner is the first operation mode, the current state is the first state, when the power-on time of the controller is not less than the set time threshold, and the operation mode of the air conditioner is the second operation mode, the current state is the second state, and when the power-on time of the controller is not less than the set time threshold, and the operation mode of the air conditioner is the third operation mode, the current state is the third state. Through this method, the current state is determined based on whether the power-on time of the controller is less than the set time threshold and the operation mode of the air conditioner, so as to further calculate the compensation temperature according to the current state, so that the calculated indoor ambient temperature can be closer to the actual indoor ambient temperature, and the accuracy of the calculated indoor ambient temperature is improved.

[0008] In addition, in the control method of the air conditioner of the present invention, the first operating mode may be a shutdown or air supply mode, the second operating mode may be a cooling, automatic cooling or dehumidification mode, and the third operating mode may be a heating or automatic heating mode.

[0009] In addition, in the control method of the air conditioner of the present invention, when the current state is the first state, the compensation temperature is the first compensation temperature, and the power-on time is t s The first setting time, the second setting time, the third setting time, the fourth setting time, and the fifth setting time are T respectively. 1 , T 2 , T 3 , T 4 , T 5 , at t s <T 1 In the case of T, the first compensation temperature is 0; 1 ≤t s <T 2 In the case of T, the first compensation temperature is 2°C; 2 ≤t s <T 3 In the case of T, the first compensation temperature is 3°C; 3 ≤t s <T 4In the case of T, the first compensation temperature is 3.5℃; 4 ≤t s <T 5 In the case of t, the first compensation temperature is 4°C; s ≥T 5 In this case, the first compensation temperature is 5° C. By using this method, when the current state is the first state, the first compensation temperature can be determined in different time intervals according to the power-on time of the controller, so that the calculated indoor ambient temperature is closer to the actual indoor ambient temperature, thereby improving the accuracy of the calculated indoor ambient temperature.

[0010] In addition, in the control method of the air conditioner of the present invention, the first set time, the second set time, the third set time, the fourth set time, and the fifth set time may be respectively T 1 , T 2 , T 3 , T 4 , T 5 , T 1 = 5 minutes, T 2 = 15 minutes, T 3 = 20 minutes, T 4 = 30 minutes, T 5 =40 minutes.

[0011] In addition, in the control method of the air conditioner of the present invention, when the current state is the second state, the compensation temperature is the second compensation temperature, and the duration of the operation mode is t o , the sixth setting time and the seventh setting time are T 6 , T 7 , at t o <T 6 In the case of T, the second compensation temperature is 3.5℃; 6 ≤t o <T 7 In the case of t o ≥T 7 In the case of the second state, the second compensation temperature is 6° C. Through this method, when the current state is the second state, the second compensation temperature can be determined in different time intervals according to the duration of the operation mode of the controller, so that the calculated indoor ambient temperature is closer to the actual indoor ambient temperature, and the accuracy of the calculated indoor ambient temperature is improved.

[0012] In addition, in the control method of the air conditioner of the present invention, the sixth set time and the seventh set time may be respectively T and T. 6 , T 7 , T 6 = 5 minutes, T7 =25 minutes.

[0013] In addition, in the control method of the air conditioner of the present invention, when the current state is the third state, the compensation temperature is the third compensation temperature, and the duration of the operation mode is t o The eighth setting time and the ninth setting time are T 8 , T 9 , at t o <T 8 In the case of T, the second compensation temperature is 5.5℃; 8 ≤t o <T 9 In the case of t o ≥T 9 In the case of the third state, the second compensation temperature is 6.5°C. Through this method, when the current state is the third state, the third compensation temperature can be determined in different time intervals according to the duration of the operation mode of the controller, so that the calculated indoor ambient temperature is closer to the actual indoor ambient temperature, and the accuracy of the calculated indoor ambient temperature is improved.

[0014] In addition, in the control method of the air conditioner of the present invention, the eighth set time and the ninth set time may be respectively T 8 , T 9 , T 8 = 15 minutes, T 9 =25 minutes.

[0023] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0024] In this specification, it should be understood that terms such as “includes,” “comprising,” and “having” refer to the existence of stated features, quantities, steps, operations, elements, parts, or a combination thereof, but do not exclude the existence of one or more other features, quantities, steps, operations, elements, parts, or a combination thereof.

[0025] <First Embodiment>

[0026] Figure 1 is a schematic flow chart of a control method for an air conditioner of the present invention, Figure 2 This is a schematic flowchart of the air conditioner control method according to the first embodiment of the present invention.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, the air conditioner includes a controller. The controller of the air conditioner can be a wire controller, but is not limited to this, and can also be a wireless controller (for example, a wireless remote control), etc., as long as it can meet the requirements for controlling the operation of the air conditioner. The air conditioner can also be controlled by a terminal device (for example, a smart phone, a desktop computer, a laptop computer, a tablet computer, a smart watch, etc.). Among them, the wire controller can be a wire controller with Wi-Fi function, a wire controller without Wi-Fi function, a wire controller connected by a cable, etc. For a wire controller with Wi-Fi function, for example, the wire controller can be controlled by a terminal device to control the operation of the air conditioner. The wire controller can be electrically connected to the indoor machine of the air conditioner and communicate with each other. In addition, the indoor machine can communicate with the terminal device, for example, and the controller can communicate with the terminal device or the indoor machine through a module for wireless communication. In addition, the wire controller can be installed on the wall of the indoor environment, etc., but is not limited to this, and can also be set in other suitable ways, as long as it can meet the requirements for controlling the operation of the air conditioner. The wireless controller can be, for example, an infrared remote control, a radio frequency remote control, etc., but is not limited to this.

[0028] The air conditioner also includes a temperature sensor, which is arranged in the controller and is used to obtain the current temperature of the controller. The air conditioner also includes a memory and a processor arranged in the air conditioner. The memory can, for example, store algorithm steps, and the processor can, for example, execute the algorithm steps to perform one or more processes of the method according to various exemplary embodiments of the present invention. The processor is configured to include a collection unit, a judgment unit, and a calculation unit. Accordingly, the method for controlling the air conditioner of the present invention using the processor includes a collection step S110, a judgment step S120, and a calculation step S130.

[0029] First, in the acquisition step (acquisition unit) S110, when the controller is powered on, the current temperature of the controller is acquired through the temperature sensor (S210), wherein the so-called controller power-on is not limited to the situation from the power supply being turned on to the system being stable and able to work, that is, not limited to the strict definition of power-on. In addition, the controller power-on includes the initial power-on of the controller and the restart power-on after power failure, and the controller starts to re-time when the above power-on begins.

[0030] Next, in the judgment step (judgment unit) S120, the current state of the air conditioner is determined based on the power-on time of the controller and the operation mode of the air conditioner. In this embodiment, the current state is determined to be the first state by judging whether the power-on time of the controller is less than the set time threshold (S220) and whether the operation mode is the first operation mode (S230). The condition for the current state to become the first state may be that the power-on time of the controller is less than the set time threshold, or the power-on time of the controller is not less than the set time threshold, and the operation mode of the air conditioner is the first operation mode. Among them, the first operation mode may be a shutdown or air supply mode. The processor may, for example, communicate with the indoor unit, the controller, the terminal device, etc. to obtain data related to the operation mode of the air conditioner, but is not limited thereto, and may also obtain information related to the operation mode of the air conditioner in other suitable ways, as long as the requirements for controlling the operation of the air conditioner can be met. According to the characteristics and use environment of the air conditioner of the present invention, the set time threshold may be, for example, 40 minutes, but is not limited thereto, and may also be other suitable values, as long as the requirements for controlling the operation of the air conditioner can be met.

[0031] Finally, in the calculation step (calculation unit) S130, the compensation temperature is determined according to at least one of the current state and the power-on time of the controller and the duration of the operation mode, and the difference between the current temperature and the compensation temperature is calculated as the indoor ambient temperature. In this embodiment, corresponding to the current state being the first state, the first compensation temperature calculation method is used to determine the first compensation temperature (S240). When the current state is the first state, the compensation temperature is the first compensation temperature, and the power-on time is ts The first setting time, the second setting time, the third setting time, the fourth setting time, and the fifth setting time are T respectively. 1 , T 2 , T 3 , T 4 , T 5 According to the characteristics and use environment of the air conditioner of the present invention, the first compensation temperature can be calculated by, for example, the following method, namely, the first compensation temperature calculation method: s <T 1 In the case of T, the first compensation temperature is 0; 1 ≤t s <T 2 In the case of T, the first compensation temperature is 2°C; 2 ≤t s <T 3 In the case of T, the first compensation temperature is 3°C; 3 ≤t s <T 4 In the case of T, the first compensation temperature is 3.5℃; 4 ≤t s <T 5 In the case of t s ≥T 5 In this case, the first compensation temperature is 5°C.

[0032] In addition, in the present embodiment, a storage step (storage unit) may also be included. The memory pre-stores compensated temperature data determined based on various models of air conditioners, etc. In addition, the compensated temperature data may be a value based on at least one of the power-on time of the controller, the operating mode of the air conditioner, and the duration of the operating mode. In addition, the memory may also store, for example, a set time threshold, a set time (for example, a first set time, a second set time, a third set time, etc.). The memory is, for example, a non-volatile memory such as an HDD (Hard Disk Drive) or a flash memory (SSD; Solid State Drive), or other solid state memory. Algorithm steps, various applications, various data, etc. are stored in the memory. The memory may also have a database, which is used as needed. In addition, the database may also be stored in a storage device or server externally connected to the server, rather than being stored in the memory.

[0033] The above-mentioned various values ​​(data) of the first compensation temperature are only an example, and may vary according to the model of the air conditioner, etc., and are not limited to the above-mentioned values. In addition, the above-mentioned various values ​​(data) of the first compensation temperature can be obtained in advance through experiments, simulations, etc. and stored in a memory. In the calculation step (calculation unit) S130, the above-mentioned various values ​​(data) of the first compensation temperature can be obtained from the compensation temperature data stored in the memory by, for example, a table lookup method, a search method, etc. according to at least one of the current state, the power-on time of the controller, and the duration of the operation mode.

[0034] In addition, the first set time T 1 , the second set time T 2 , the third setting time T 3 , the fourth setting time T 4 , the fifth setting time T 5 For example, it can be T 1 = 5 minutes, T 2 = 15 minutes, T 3 = 20 minutes, T 4 = 30 minutes, T 5 =40 minutes, but not limited thereto, and may also be other appropriate values ​​as long as the requirements for controlling the operation of the air conditioner can be met.

[0035] In this embodiment, after the controller is powered on, when the controller power-on time is less than the set time threshold, or when the controller power-on time is not less than the set time threshold, and the operation mode is the first operation mode (for example, shutdown or air supply mode), the controller's self-heating increases with the power-on time, and the compensation temperature also increases with the power-on time. When the power-on time reaches the time threshold, for example, 40 minutes, the controller's self-heating is stable, and the compensation temperature also tends to be stable.

[0036] The current state when the power-on time of the controller is less than the set time threshold is the same as the current state when the power-on time of the controller is not less than the set time threshold and the operation mode is the first operation mode. When the current states are the same, the compensation temperature corresponding to the power-on time of the controller or the duration of the operation mode is the same.

[0037] <Second Embodiment>

[0038] Figure 3 This is a schematic flowchart of a control method for an air conditioner according to a second embodiment of the present invention.

[0039] like Figure 3As shown, the difference between the second embodiment and the first embodiment is that in the judgment step (judgment unit) S120 of this embodiment, by judging whether the power-on time of the controller is less than the set time threshold (S320) and whether the operation mode is the second operation mode (S330), it is determined that the current state is the second state. The condition for the current state to become the second state may be that the power-on time of the controller is not less than the set time threshold and the operation mode of the air conditioner is the second operation mode. Among them, the second operation mode can be cooling, automatic cooling or dehumidification mode. The so-called automatic cooling means that the air conditioner automatically cools according to conditions such as the indoor ambient temperature.

[0040] In the operation step (operation unit) S130 of this embodiment, corresponding to the current state being the second state, the second compensation temperature calculation method is used to determine the second compensation temperature (S340). When the current state is the second state, the compensation temperature is the second compensation temperature, and the duration of the operation mode is t o , the sixth setting time and the seventh setting time are T 6 , T 7 According to the characteristics and use environment of the air conditioner of the present invention, the second compensation temperature can be calculated by, for example, the following method, i.e., the second compensation temperature calculation method: o <T 6 In the case of T, the second compensation temperature is 3.5℃; 6 ≤t o <T 7 In the case of t o ≥T 7 In this case, the second compensation temperature is 6°C.

[0041] In addition, in the present embodiment, a storage step (storage unit) may also be included. The memory pre-stores compensated temperature data determined based on various models of air conditioners, etc. In addition, the compensated temperature data may be a value based on at least one of the power-on time of the controller, the operating mode of the air conditioner, and the duration of the operating mode. In addition, the memory may also store, for example, a set time threshold, a set time (for example, a first set time, a second set time, a third set time, etc.). The memory is, for example, a non-volatile memory such as an HDD (Hard Disk Drive) or a flash memory (SSD; Solid State Drive), or other solid state memory. Algorithm steps, various applications, various data, etc. are stored in the memory. The memory may also have a database, which is used as needed. In addition, the database may also be stored in a storage device or server externally connected to the server, rather than being stored in the memory.

[0042] The above-mentioned respective values ​​(data) of the second compensation temperature are only an example and may vary according to the model of the air conditioner, etc., and are not limited to the above-mentioned values. In addition, the above-mentioned respective values ​​(data) of the second compensation temperature may be obtained in advance through experiments, simulations, etc. and stored in a memory. In the calculation step (calculation unit) S130, the above-mentioned respective values ​​(data) of the second compensation temperature may be obtained from the compensation temperature data stored in the memory by, for example, a table lookup method, a search method, etc., according to at least one of the current state, the power-on time of the controller, and the duration of the operation mode.

[0043] In addition, the sixth setting time T 6 , Seventh setting time T 7 For example, it can be T 6 = 5 minutes, T 7 = 25 minutes, but not limited thereto, and may be other suitable values ​​as long as they can meet the requirements for controlling the operation of the air conditioner. o , that is, the time the current operating mode of the air conditioner has lasted.

[0044] In this embodiment, when the controller turns on the second operating mode (for example, cooling, automatic cooling or dehumidification mode) after the power-on time reaches a set time threshold, as the indoor ambient temperature drops rapidly, the temperature of the controller changes due to the drop in the indoor ambient temperature. After the operating mode lasts for, for example, 25 minutes, the temperature of the controller tends to stabilize in the second operating mode. Therefore, the compensation temperature at this time tends to stabilize.

[0045] <Third Embodiment>

[0046] Figure 4 This is a schematic flowchart of a control method for an air conditioner according to a third embodiment of the present invention.

[0047] like Figure 4 As shown, the difference between the third embodiment and the first embodiment is that in the judgment step (judgment unit) S120 of this embodiment, by judging whether the power-on time of the controller is less than the set time threshold (S420) and whether the operation mode is the third operation mode (S430), it is determined that the current state is the third state. The condition for the current state to become the third state may be that the power-on time of the controller is not less than the set time threshold and the operation mode of the air conditioner is the third operation mode. Among them, the third operation mode can be a heating or automatic heating mode. The so-called automatic heating means that the air conditioner automatically heats according to conditions such as the indoor ambient temperature.

[0048] In the operation step (operation unit) S130 of this embodiment, corresponding to the current state being the third state, the third compensation temperature calculation method is used to determine the third compensation temperature (S440). When the current state is the third state, the compensation temperature is the third compensation temperature, and the duration of the operation mode is t o The eighth setting time and the ninth setting time are T 8 , T 9 According to the characteristics and use environment of the air conditioner of the present invention, the third compensation temperature can be calculated by, for example, the following method, namely, the third compensation temperature calculation method: o <T 8 In the case of T 8 ≤t o <T 9 In the case of t o ≥T 9 In this case, the third compensation temperature is 6.5°C.

[0049] In addition, in the present embodiment, a storage step (storage unit) may also be included. The memory pre-stores compensated temperature data determined based on various models of air conditioners, etc. In addition, the compensated temperature data may be a value based on at least one of the power-on time of the controller, the operating mode of the air conditioner, and the duration of the operating mode. In addition, the memory may also store, for example, a set time threshold, a set time (for example, a first set time, a second set time, a third set time, etc.). The memory is, for example, a non-volatile memory such as an HDD (Hard Disk Drive) or a flash memory (SSD; Solid State Drive), or other solid state memory. Algorithm steps, various applications, various data, etc. are stored in the memory. The memory may also have a database, which is used as needed. In addition, the database may also be stored in a storage device or server externally connected to the server, rather than being stored in the memory.

[0050] The above-mentioned respective values ​​(data) of the third compensation temperature are only an example and may vary according to the model of the air conditioner, etc., and are not limited to the above-mentioned values. In addition, the above-mentioned respective values ​​(data) of the third compensation temperature may be obtained in advance through experiments, simulations, etc. and stored in a memory. In the calculation step (calculation unit) S130, the above-mentioned respective values ​​(data) of the third compensation temperature may be obtained from the compensation temperature data stored in the memory by, for example, a table lookup method, a search method, etc., according to at least one of the current state, the power-on time of the controller, and the duration of the operation mode.

[0051] In addition, the eighth setting time T 8, Ninth setting time T 9 For example, it can be T 8 = 15 minutes, T 9 = 25 minutes, but not limited thereto, and may be other suitable values ​​as long as they can meet the requirements for controlling the operation of the air conditioner. o , that is, the time the current operating mode of the air conditioner has lasted.

[0052] In this embodiment, when the controller turns on the third operating mode (for example, heating or automatic heating mode) after the power-on time reaches a set time threshold, as the indoor ambient temperature increases, the temperature of the controller changes due to the increase in the indoor ambient temperature. After the operating mode lasts for, for example, 25 minutes, the temperature of the controller tends to stabilize in the third operating mode. Therefore, the compensation temperature at this time tends to stabilize.

[0053] Although the present invention is specifically described above in conjunction with the accompanying drawings and embodiments, it is to be understood that the above description does not limit the present invention in any form. Those skilled in the art may deform and change the present invention as needed without departing from the essential spirit and scope of the present invention, and these deformations and changes all fall within the scope of the present invention.
